Detailed Description
template<typename PointT, typename LeafContainerT = OctreePointCloudAdjacencyContainer<PointT>, typename BranchContainerT = OctreeContainerEmpty>
class pcl::octree::OctreePointCloudAdjacency< PointT, LeafContainerT, BranchContainerT >
Octree pointcloud voxel class which maintains adjacency information for its voxels.
This pointcloud octree class generates an octree from a point cloud (zero-copy). The octree pointcloud is initialized with its voxel resolution. Its bounding box is automatically adjusted or can be predefined.
The OctreePointCloudAdjacencyContainer class can be used to store data in leaf nodes.
An optional transform function can be provided which changes how the voxel grid is computed - this can be used to, for example, make voxel bins larger as they increase in distance from the origin (camera).
- Note
- See SupervoxelClustering for an example of how to provide a transform function.

◆ getLeafContainerAtPoint()
| LeafContainerT * pcl::octree::OctreePointCloudAdjacency< PointT, LeafContainerT, BranchContainerT >::getLeafContainerAtPoint | ( | const PointT & | point_arg | ) | const |
Gets the leaf container for a given point.
- Parameters
-
[in] point_arg Point to search for
- Returns
- Pointer to the leaf container - null if no leaf container found.

◆ setTransformFunction()
|
inline |
Sets a point transform (and inverse) used to transform the space of the input cloud.
This is useful for changing how adjacency is calculated - such as relaxing the adjacency criterion for points further from the camera.
- Parameters
-
[in] transform_func A boost:function pointer to the transform to be used. The transform must have one parameter (a point) which it modifies in place.

||
| ) |
Tests whether input point is occluded from specified camera point by other voxels.
- Parameters
-
[in] point_arg Point to test for [in] camera_pos Position of camera, defaults to origin
- Returns
- True if path to camera is blocked by a voxel, false otherwise.
